学习用于数据分析的python - datetime.datetime模块的问题

Question

import pandas_datareader as pdweb
import datetime
Stock_prices = pdweb.get_data_yahoo(["AAPL", "RIL", "TSLA"], start = datetime.datetime(2012,1,1), end = datetime.datetime(2018,1,1) ["Adj Close"])

我得到的错误：

类型错误回溯(上次调用的最近一次( 在 ----> 1 Stock_prices = pdweb.get_data_yahoo(["AAPL"， "RIL"， "TSLA"]， 开始 = datetime.datetime(2012,1,1(， end = datetime.datetime(2018,1,1( ["Adj Close"](

类型错误："datetime.datetime"对象不可下标

Answer 1

只需这样做：

Stock_prices = pdweb.get_data_yahoo(["AAPL", "RIL", "TSLA"], start = datetime.datetime(2012,1,1), end = datetime.datetime(2018,1,1))['Adj Close']

或

Stock_prices = pdweb.get_data_yahoo(["AAPL", "RIL", "TSLA"], start = datetime.datetime(2012,1,1), end = datetime.datetime(2018,1,1))
print(Stock_prices['Adj Close'])

Answer 2

看起来不对的是end = datetime.datetime(2018,1,1) ["Adj Close"]。您是否有可能缺少昏迷分隔符？
